333342 divided by 19 
The aim is to understand the frequency of 19 in 333342.

On to step 1:
3 divided by 19 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 19

Going ahead to step 2:
19 goes into 33 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 19 from 33, we get 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 19

Going ahead to step 3:
19 can be fit into 143 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 133 from 143 to get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 19

Let's proceed to step 4:
103 divided by 19 is 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
Subtract 95 from 103 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 19

Moving on to step 5:
19 can be fit into 84 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1754.0
If we take 76 away from 84, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 19

On to step 6:
The number 19 fits into 82 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 17544.0
If we take 76 away from 82, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 19 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 17544.3
Subtracting 57 from 60 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 17544.31
Subtract 19 from 30 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
The number 19 fits into 110 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 17544.315
Subtracting 95 from 110 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
19 can be fit into 150 7 times, resulting in a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 17544.3157
Deduct 133 from 150 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
19 goes into 170 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 17544.31578
If we subtract 152 from 170, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
When dividing 180 by 19, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 17544.315789
Subtracting 171 from 180 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
19 goes into 90 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 17544.3157894
If we take 76 away from 90, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
140 divided by 19 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 17544.31578947
If we take 133 away from 140, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 17544.31578947 and a remainder of 7e-09.
